Is it dangerous to drive with high tire pressure?
1 Answers
When the tire pressure is too high, it reduces the contact area between the tire and the ground, increases the pressure on the tire, and affects the tire's grip. When the vehicle passes over bumpy roads, it causes greater impact on the suspension system and increases the risk of a tire blowout. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; increases body vibration, indirectly affecting the lifespan of other components; it causes excessive stretching and deformation of the tire cords, reducing the tire's elasticity and increasing the load on the vehicle while driving; puncture resistance decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts. Hazards of insufficient tire pressure: Increases the friction coefficient with the road surface, leading to higher fuel consumption; causes the steering wheel to feel heavy and prone to deviation, which are factors detrimental to driving safety; increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; increases tire body deformation, making the tire side prone to cracks and generating flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
